Method for generating audio signal using plurality of speakers and microphones and electronic device thereof

A method for canceling an echo in an electronic device, the method comprising:

• outputting a first output audio signal on a first band, via a first speaker;
• outputting a second output audio signal on a second band, via a second speaker;
• identifying a first partial audio signal on the second band within a first input audio signal obtained through a first microphone;
• identifying a second partial audio signal on the first band within a second input audio signal obtained through a second microphone;
• providing a transmission audio signal, based at least on the first partial audio signal and the second partial audio signal;
• and
• transmitting information about the transmission audio signal to an external electronic device.

An electronic device comprising:

• a housing;
• a communication module;
• a first speaker disposed in a first region of the housing;
• a second speaker disposed in a second region of the housing;
• a first microphone disposed adjacent to the first region;
• a second microphone disposed adjacent to the second region;
• and
• a processor,
• wherein the processor is configured to:
• receive a first audio signal from an external electronic device, by using the communication module;
• output a first given frequency band among a frequency band of the first audio signal by using the first speaker, and output a second given frequency band among the frequency band of the first audio signal by using the second speaker;
• provide a first signal by applying a filter capable of passing a band corresponding to the second given frequency band to an audio signal external to the electronic device which is acquired using the first microphone, and provide a second signal by applying a filter capable of passing a band corresponding to the first given frequency band to the audio signal external to the electronic device which is acquired using the second microphone;
• provide a second audio signal corresponding to the external audio signal by using the first signal and the second signal;
• and
• transmit the second audio signal to the external electronic device by using the communication module.
